5 Claims. Cl. 14640) The present invention relates to improvements in culinary devices and more'particularly to a device which is adapted to peel, core, slice and dice vegetables or fruit. An object of the present invention is to provide 'a novel culinary device which is adapted to be secured to a table or the like and which is manually operable for effectively peeling vegetables and fruit.

'A further object of the present invention resides in the novel construction of a culinary device whereby one object may be peeled while a second object is being cored, sliced and diced. I

A further object of the present invention is to provide a novel coring devicewhereby' initial movement of the coring meanseflectsfremoval of the core of the object while continued movement of the coring device eflects releasing of the coring tube, whereby the coring tube holder may continue to move'against the object for forcing itjthrough a plate grid for slicing the object.

"Still another object of the present invention is to provide a novel cooperation between a cutting blade whereby, as an object is forced'thro'ugh a slicing grid, the cutter will efiect dicing of the slices.

A still further object of the present invention is to provide a novelend plate for the frame whereby plate grids of various'forms'maybe removably positioned for slicing the fruit or vegetable object as desired. v

A further object of the present invention is to provide Patented Nov. 2, 1954 meral 10 designates generally the mounting means for supporting the structure of the present invention, the numeral 12 designates generally the frame supported by the mounting means 10, the numeral 14 designates generally the manual operating means, the numeral 16 designates generally the means mounted on the frame and actuated by the operating means for longitudinally moving the peeling and coring means, while the numerals 18 and 20 designate generally the peeling and coring means respectively, and the numeral 22 designates generally the plate grid means employed for slicing the fruit or vegetable objects.

Looking now at Figures 1 and 2, the mounting means 10 will be best seen as comprising a standard 24 having a C-clamp base 26. One arm of the C-clamp 26 is provided with a sleeve end 28 which is internally threaded for receiving the clamping element 30 which is provided with a flattened head 32. The upper end of the standard 24 is of enlarged area at 34 and has a pair of apertures 36 formed therein. The manner in which the mounting means 10 is secured to a table or the like 38 will be readily seen in Figure l, and since such means are conventional, further description thereof is deemed unnecessary.

The frame means 12 is mounted for support-by the mounting means 10 in the following manner. One end of the frame 12 is comprised of a housing 40 having a 7 longitudinally extending inner'wall 42. The inner wall 42 an arrangement whereby apeelingblade is. longitudinally moved as the fruitor vegetable -object is rotated, and wherein the peeling blade is resiliently pivotally mounted for manual movement to engagement with the fruit or vegetable objectfor peeling of the same.

r Various other objects and advantages'will become apparent from the detailed description to follow. The best form in which I have contemplated applying my invention is clearly illustrated in the accompanying drawings, wherein:

'Figure 13 is an enlarged detailto'p plan view of the peeling and coring means.

'Referring more particularly to the drawings, wherein like'numerals designate likeparts throughout, the nulongitudinally extending support bars 50 and 52 which maintain the housing 40 and end wall 48 in fixed spaced relation.

The end wall 48 is best seen in Figure 4 and is of substantially elongated form at 54 and 56 with anenlarged portion at 58, the enlarged'portion at 58 being provided with a substantially circular opening for receiving the slicer means to be hereinafter described. The enlarged portion 58 is provided with a boss at 60 with a set screw 62 threadably mounted therein and extending to the interior opening 64. The elongated portions 54 and 56 of the end wall 48 are provided with a plurality of bores 66, 68, 70 and 72. The bores 70 and 72 are adapted to receive the shafts 50 and 52 which are fixedly mounted therein. The bore 68 is adapted to receive the worm 74 for free rotation therein, while the bore 66 is adapted to slidably and adjustably receive the bar- 76 which is for a purpose to be hereinafter described.

The slicing means 22 may be of various forms such as is shown in Figures 4, 8 and 10. Each of the slicing means 22 is comprised of an outer cylindrical element 78 and a plurality of grid plates 80 integrally formed with the cylindrical element 78. In Figure 4, the plates 80 are all parallel to each other and are adapted to slice the fruit or vegetable object as it moves longitudinally therethrough. In the form of Figure 8, the slicing means 22 is comprised of the cylindrical element 78' formed with a plurality of vertically extending grid plates 80' and also a plurality of horizontally extending grid plates 81, whereby the fruit or vegetable object passing therethrough will be sliced along a plurality of vertically and horizontally extending planes. Similarly, the form disclosed in Figure 10 is formed from a cylindrical element 79 with a single vertically extending grid plate 88" and a single horizontally extending grid plate 81. The center portions of the vertically and horizontally extending grid plates 80" and 81 are integrally formed with a substantially cylindrical element 82. The cylindrical element 82 has a gradually diametrically reduced extension 84 to which is integrally attached a pin 86 at its inner end.

It will be readily seen that any of the slicing means 22 shown may be positioned within the enlarged portion 58 of the end wall 48 and clamped therein by means of the set screw 62. Of course, various other forms of slicing means may be employed.

The housing 40 is of substantially elongated form and is provided with a pair of bores 88 and 90 which are in is'provided with a bearing exten'sion 106 which is rotat ably supportedtby thebores 102 and 104. An arcuated handle element.108 is fixedly secured to the outer end of the extension 106 by means of the set screw or pin 110. Thehandlefor thermanual operating means 14 is best shown in Figures 1 and 2 ,as comprising an elongated flatstrap 110 which istformed with'an elongated slot 112. A handle 114 -is rotatablytsecured' to the lower end of the strap 110by-anyconventional-.means. A screw 116 is -formed the. arcuatedelement 108,- extending therefrom 1 and being, receivable-.- in the I elongated slot 112 whereby a wing nut vlls may ,be threadably secured thereon for clamping thehandle 114. the desired distance from 1116131115 or": rotation top give satisfactory leverage means.-

The housingAiiwis also provided-with an internally extendingboss 120 which is provided with a bore 122'which is in axial alignment with another bore 124'in the wall portion 94; Anbar 77 iszrotatablydisposedin the bores 122 'and 124fiand has a. collan 126 securely mounted there on betweenthe boss 120 and thesprocket "128. Asimilar collar -126':=-is securedgtoathe'extension .106 of the worm shafts M50. and..52 for..sliding"and.supportingengagement. on the shafts. It will thus be seen that the peeling means 18 and coring means 20 will be longitudinally moved upon rotation of the worm 74, since the block 144 will be held from rotation therewith by means of the plate 148 slidingly engaged on the shafts 50 and 52. Fixedly mounted on th'eablock 144 is the tubular housing 158. in. whichis reciprocably mounted ..a pin 160 -whichis adaptedgtof'extend :through the block 144 for engagement with the-threads"of the worm 74.

If it be desired to employ the peeling means-18, the-disk 234 is urged inwardly, thereby removing :the angulated end 230 from engagement underneath the arm 224-and" also disengaging the gear 236 from the dog 238. The arm 224 will then be free to beresiliently urged downwardly for engagement with a fruit or vegetable object.

The peeler means :18 is;comprised ,of ,a framework 241 which is integrally formed with the arm 224 and has a pair of spaced bars 242 and 246. A rod 248 is swivellymounted in apertures in the bars 242 and 246 and a spacer sleeve 250 is pinned to the rod 248 and mounted between the bars-2423and 246 for maintaining the rod 248 in predetermined-relation to the Secured tothe outer end of the rod 248 is the peeler element 252 having a slot'254 provided with a cutting edge 256 for engagement with the object to be peeled. A handle element 258 extends from the peelmg element 252 and terminates in an arcuated wire 260 which is adapted to be manually engaged for effecting peeling of the object.

Looking now at Figures 1 and 4, it will be seen that a bracket 262 is secured in upstanding relation to the enlarged portion 58 of the end wall 48. Longitudinally extending therefrom and fixedly secured to the upstanding bracket 262 is a flat elongated bar 264 which is providedwith a laterally extending pin 266 adjacent one end.

As seen in Figure 6, a rod 268 is transversely disposed and rotatably mounted within a pair of sleeves 270 which are fixedly secured to the plate 172. The rod 268 has a laterally extending clamp 272 mounted there on for engagement with the bight portion 274 of the U-shaped member 202. The extremity of the rod 268 is provided with an upstanding trip rod 276 and an arcuated rod 278 which is disposed at substantially a right angle with respect to the upstanding rod 276.

It will readily be seen from an examination of Figure 1 that as the supporting mechanism for the coring device and the peeling means are moved longitudinally on the frame and worm, the upstanding rod 276 will engage the pin 266 on the longitudinally extending bar 264, thereby eflecting pivoting movement of the rod 268 and clamp 272. As a result thereof, the bight portion 274 of the U-shaped element 202 will be moved upwardly and the cam surfaces 214 and 212 will engage the enlarged heads 198 on the pins 194 and 196, urging them outwardly and efiectingoutward movement of the angulated plates 184 and 186. The outward movement will retract the angulated plates from the annular groove 188 in the coring tube 176.

In view of the foregoing, one skilled in the art will readily understand the operation of the coring and slicing means. Initial longitudinal movement of the coring means 20 will effect coring of the object in the manner shown in Figure 3. Continued movement of the coring means will complete coring of the object and the coring tube 176 will approach the slicing means 22 as a limit. At this time, the upstanding rod 276 will engage the pin 266 and will be pivoted thereby and will release the coring tube 176 as hereinabove set forth. Thus, continued movement of the cup 178 will be permitted until the flattened end 180 of the cup 178 engages the object being cored. Thereupon, the object will be forced through the slicing means 22 to be divided into a plurality of parts.

The actuating means for effecting longitudinal movement of the coring and peeling means and for rotating the object being peeled should be obvious from the drawings and the above description. The handle 114 is rotated and the worm 74 and parallel rod 77 will be simultaneously rotated by means of the chain 132. Thus, the object being peeled will be rotated with the rod 77 and the peeling means 18 and coring means 20 will move longitudinally on the worm 74 as above described. As the peeling means 18 moves over the vegetable or fruit which is to bepeeled, the handle 260 is manipulated so that the cutting blade 256 removes the peeling from the object. Since the peeling element 252 isswivelly mounted withrespect to" the arm 224, it ispossible to efiectively remove the peeling from the object regardless of the contour thereof.

. Referrmg once again to Figure 3,. it will be seen that as the fruit or vegetable is forced through the slicing means 22, .the cutter blade will. be rotated with the .worm- 74 and will transversely cut "the ObjGCt to produce diced pieces. Of course, as above stated, a cutter blade such as 134'. shown in Figure 9 couldbe substituted for the-single blade 140, and since the number of times an individual blade passes the sliding means 22 will .be increased, the object will be cut a greater number of times in a transverse direction.

From the foregoing description, taken in conjunction with the drawings, it is believed that a device'has been provided which will accomplish all of the object's hereinabove set forth.
